Here's some pics for reference @JonCreighton 
have most of the intake blocked off for the winter months and we are going to extend the walls down a bit further so the cold air comes underneath the tables

this is very dependant on the distance from the canopy.... ppfd is where u want to be for measureing light... u can probable get that info from the specs.... u can be pushing 900 w at 1 ft and be at 1 ppfd of 1000... and u can be pushing 900w at 2 ft away and be at 500ppfd.. thats half the light half the energy half the yield.... i would check w the LED manufactorer to see whats the distance they recommend for that wattage... if ur lights are a ft higher than reccomened.. ur going to getting half the power... im not sure how this works ina mixed room... but keep in mind also the hps is putting down more ir than the LEDs... if there the same distance away ur going to have different leaf temps... i think

I've been thinking of that, also they are cmh not led, and 81 seems to be the sweet spot, also lowering my lights anymore is literally impossible as they sit a half inch above my racks now amd if I lower my cmh anymore it will burn down my house I already almost proved that lowering my lights

do u ever think of closing the system and adding co2. u could push ur lights about 1.5x harder.. and all the other limiting factors go up so its really a game changer
also if ur running those ACs while its an opeen systeem they have to fight the fresh air ud be cycling in or pulling out... so they shouldnt run all that much more if its closed as they are just treating the same air every so often.... also an open system ambient co2 is something aournd 78f - 60 humidity... w supplimental co2 u can run temps up as high as 86-87 and humiditys in the 70s.... so u might actually put less strain on that stuff.. im just saying it looks like u have the infa structure to suppliment co2.. u might be able to double yield
i think the most up to date data or the stuff i trust the most would say this graph is extremely constvative... as in thosee lines should keep going up for a little more before they flatten off but it shows how important co2 is w light intensity

I am in this with my family and convincing the other 2 to do co2 is a nightmare but I really want to either do that or rip off half the garage and greenhouse it out
